Disco trigger problems

[BC81]

I like Magnum Air Power's hardened stainless sears.

Have them on 3 guns.

Those are nice, so are the right size stainless sears that David over at AlchemyAir sells

I even use them on my Blue Fork trigger assemblies; I have 2:

Are these still in production? Haven't seen those in ages

[Rick67]

I bought them from HPA Sports, as the maker is not really trustworthy.

They were, at one time, black, but I had them nickel boron plated by CCR:

I think the maker still makes them every now and then.

The markings on the new batch are ugly though and looks like they were manually punched, yuck!

Ok here is what I did.  I bent the spring for a little more tension and dressed up the top and front of the sear.  Seems to work fine but I dont trust it as of yet.  Fired about 20 rounds over the chrony at about 860fps.  So far so good.

Now where do I get another spring and sear? Tried looking on Crosman but cant find the link.  I know that sounds dumb but for some reason cant find the link for parts.  I wanted to get them from Crosman,  I would rather put new parts in it.  I may shoot it this way for a while.  I think I'm looking for the spring and bar. Sorry not sure of the name of that thing.

Now the screws for the cover really a bit loose.  Yes I was very careful not to strip them but they hardly even snug the screws.  What do you guys do to get the screws a little tighter?  I was thinking a bit of cotton in the hold and screw in on that.

Here is the EVP

I believe you gotta call the parts department still, that's what I do. Give customer service the part numbers and pay over the phone. You will pay 4x the price from other vendors and I doubt you'll even find the safety spring. That's the spring you need. Itll be fine for shooting til they come in, but it wouldn't hurt to get new ones. As for the cover screws, I've never had them be loose. You could file the ends of them down, the flat end that goes into the hole. Just don't hit the threads. That will shorten them a bit and make them seat deeper. If they have side to side play, a little drop of glue in the holes or thread tape.  Not really much room with all that small plastic stuff to shim anything.
You could order an Mrod trigger and challenger trigger guard and really upgrade that trigger lol. Need 2 brass washers between the housing and tube at the mounting holes to shim it out to the correct depth. .030" thickness and size 8 hole should do it... im trying to make you spend some money now lol

The problem is the screws were stripped from the factory.  They hold the plate on but I cant get it tight.  Or should I say plastic tight. LOL 

Now your trying to get me in trouble. LOL  Yeah I may do the mrod trigger later but want to get this up and running for now.  I have way to much money in this thing now. LOL Maybe not what you guys have but to me its a lot.  I could have bought a Marauder for the money I have in this thing.  If it comes to a new trigger ok but as they say for now "Run watcha brung" LOL

[BC81]

Oh I get that. The stock trigger can be made pretty good with the 3 screw mod and a light spring from a Bic pen. I would put a drop of Elmer's glue or wood glue in each screw hole, put the assembly all back together and screw the screw down just shy of tight. Wait about 20 minutes and then tighten down a bit. That should let the glue fill in the sloppy areas and dry, but not a strong enough adhesive to weld it together lol

Yeah thats it the tricks of the trade.  This will break loose when i go back in later to put in the new spring and sear right?  Its a mod of the old tooth pick in the hole trick but for plastic, LOL  Thanks

[BC81]

Yeah, thats why I was saying a drop of Elmer's or somehow strength. I forgot about the tooth pick trick!

Yeah I though maybe a little cotton to take up the slack.  Anyway It worked for about 20 shots then back to the same problem.  I have a spring and sear ordered from a guy on the forum.  I have to get to the shop and take another look.  It maybe the cover is working loose after a few shots and the cantilever and sear have to much movement and slid over each other.  Idono.  Maybe the Marauder trigger is in the future. LOL 

[BC81]

If the cover is that sloppy it could be the issue, ive never encountered that myself though. Good luck!

Tried it again.  Bent the trigger spring out more.  Dressed the face of the sear although not sure thats the problem.  Tried it again.  Seems to work.  fired 20 or more shots without a problem.  The problem is the trigger pull is now awful.  I can only get the mid 700fps using 14.3 crosman domes.  If I adjust the hammer spring any tighter it won't cock.  I think the cover for the trigger is a non issue.  It fits tight enough in the stock to hold things together.  I put two wraps of electrical tape around it to hold the cover tight and it just I mean just got in the stock.  The cover really isn't sloppy but I cant get it snug. It won't fit quite flat across the housing.
Not sure why I cant get the power up a bit.  When I increase it will not cock.  Oh well fix one create another. LOL

 Is something hanging up in the hammer/ hammer spring area

Well I did notice the hammer is a bit dry.  Next time out I think I put a little lube on it.

Maybe your hammer spring has been too tight from the beginning causing all your issues.

Thanks yep checked that out in the beginning.  After I finished with the mods, a few years ago, I noticed I could get to much pressure on the spring and it wouldn't cock.  I had to back off for the sear to lock up.  I did the same thing this time.  After the problem started I went way out on the spring then brought it in until I know I was in good territory.  Still would lockup.  Cant swear to it but it seems to be holding but........ the trigger is way to heavy and the velocity is not where I would like it.  Not looking for a cannon but would ike to be in the mid 800's.  As was suggested earlier I think the trigger spring pressure was a bit low.  Of course when I check it again later it may not work. LOL

Order a new frame/housing, sear and spring from Crosman.
